FreeRTOS V812 portmacro.h: missing binary operator before token “long”
Hi,
Using the new version of FreeRTOS I get always this error:
Source/portable/GCC/ARM_CM3/portmacro.h:91:23: error: missing binary operator before token “long”
~~~~~~~~~~~~~~~~~~
/* Type definitions. */
FreeRTOS V812 portmacro.h: missing binary operator before token “long”
The error doesn’t seem to make any sense when viewed in isolation as ‘long’ is obviously a standard C type, but this is a #define so the error must be coming from where the #define is actually used in the source code. Which file is being compiled when portmacro.h gets included? Maybe it would help if you posted the all the compiler output (not of the whole build – just the output when you try recompiling after this error has been output).
Regards.

Here is the compilation error (removed some path data for confidentiality)

Oups, there is also:
/frtos/Source/include/FreeRTOSConfig.h:74:44: note: in expansion of macro ‘portBASETYPE’
#define configMAXPRIORITIES ( ( unsigned portBASETYPE ) 8 )
^
/frtos/Source/portable/GCC/ARMCM3/portmacro.h:166:7: note: in expansion of macro ‘configMAXPRIORITIES’
#if( configMAXPRIORITIES > 32 )

Very curious – it is compiling heap3.c, but heap3.c does not make any
reference to portLONG. In fact, portLONG has not been used in the code
for a very long time and its definition is just maintained for backward
compatibility with some old demos.
Is it possible there are some version mismatches somewhere? What is the
version number at the top of heap_3.c?
Regards.

That one is not so mysterious. Just take the cast off the front of the 8, so it becomes:
#define configMAX_PRIORITIES ( 8 )

Thank you, it works. I’ve learned something today 🙂
